'Note that the comparison operations on  may diverge < since it is (by necessity) impossible to implementent them # correctly and always terminating. *This implementation is really David Lester's ERA package. GHIJKLMNOPQRSTUVThe  function connverts a  to a W. The number of decimals The real number The resulting string XYZ[\ The - type is the type of differentiable numbers.  It'0s an instance of all the usual numeric classes. 5 The computed derivative of a function is is correct = except where the function is discontinuous, at these points 3 the derivative should be a Dirac pulse, but it isn't. The + numbers are printed with a trailing ~~ to  indicate that there is a "tail" of derivatives. ]^The ' function turns a normal number into a  8 number with the same value. Not that numeric literals 6 do not need an explicit conversion due to the normal " Haskell overloading of literals. The ) function turns a number into a variable 8 number. This is the number with with respect to which  the derivaticve is computed. The  takes a  number and returns its first 5 derivative. The function can be iterated to to get  higher derivaties. The  function takes a  number back to a normal 4 number, thus forgetting about all the derivatives. The  takes a value and  value and makes  a / number that has the given value as its normal  value, and the  number as its derivatives. The * function is a simple utility to take the - derivative of a (single argument) function.  It is simply defined as  deriv f = val . df . f . dVar  Convert a # function to an ordinary function. _ `abcde      !"#$%&'()*+,-./0123456789:;<=>?@ABCDEFG-HIJKLMNOPQRSTUVWXYZ[\]^L_`abcdefghijklmnnumbers-2007.9.23Data.Number.IntervalData.Number.FixedData.Number.BigFloatData.Number.CRealData.Number.DifData.Number.SymbolicData.Number.VectorspaceData.Number.FixedFunctionsIntervalivalgetIvalFixed PrecPlus20Prec50Prec10EpsDiv10Eps1Epsilon precision convertFixed dynamicEpsBigFloatCReal showCRealDifdCondVardfvalmkDifderivunDifSymvarconsubstunSym Vectorspace*><+>vnegatevzeroICFapproxfromCFtoCFapproxCFfac integerRoot2pitansincosatanasinacossqrtexpcoshsinhtanhatanhasinhacoshlogfromTaylorToCFFPrec500epslift2getEpstoFixed0toFixed1BFbasebftoFloat1CRdiv2nmul2nacc_seqexp_drlog_drlog_drxsin_drcos_dratan_dratan_drx power_seriespiBy2piBy4log2sqrt1By2GHC.BaseString digitsToBitsdigits sizeinbase floorsqrtround_ukCDliftAppConbinOpunOpisCon
